Inventory of Flood-Sensitive and Flood-Resistant Flowering Plants
Main content introduction: This article covers knowledge related to common gardening practices, including an inventory of flood-sensitive and flood-resistant flowering plants, with specific details as follows:
All cacti and succulent plants are drought-resistant and fear flooding, such as cacti, cacti species, aloe vera, Hens and Chicks, Echeveria, etc. If the potting soil remains moist for too long or gets soaked by rain, it is prone to leaf rot and root rot. Flesh-rooted and bulbous plants like orchids, peonies, Chinese peonies, kaffir lilies, dahlia, tuberous begonias, lucky grass, cyclamen, and鹤望兰 (Crane flower) etc., are prone to death due to flooding.
Some woody flowers are also very susceptible to flooding, such as plum blossoms, peach trees, osmanthus, azaleas, wintersweet, laughing orchid, bougainvillea, Norfolk Island pine, Brazil wood, golden edge fragrant osmanthus, and begonia species, etc. If they are waterlogged for 3-5 days, they will be in critical condition and difficult to save.
Some moisture-loving flowers also fear waterlogging, such as chrysanthemums, jasmines, aglaia, and asparagus ferns, etc. If the potting soil is too warm or gets soaked by rain for a long time, the roots will suffocate and die. To prevent flowering plants from suffering from flooding, the following measures have been taken by the author:
(1) Flood-sensitive terrestrial plants should be planted in well-drained, elevated areas, and never in low-lying areas.
(2) For terrestrial plants at risk of flooding, drainage ditches should be dug before the rainy season arrives. The root area should be mounded up, and valuable trees should be wrapped in plastic sheeting after mounding.
(3) During the plum rain season, potted flowers should be moved to a sheltered area as early as possible. If there are too many potted plants to move, they should be tilted to prevent water accumulation.
(4) For potted plants, the bottom drainage holes should be enlarged, covered with a piece of window screen, and then a layer of brick, charcoal, or charcoal chunks the size of a date pit should be added to allow excess water to drain out. For flood-averse terrestrial plants, a deep hole should be dug before planting, with a thick layer of gravel or charcoal chunks placed at the bottom to facilitate water渗透.
(5) When watering flood-averse plants, it is essential to follow the principle of "drying and wetting," using more spraying and less灌溉. When watering, prevent "waist-high water" and avoid water accumulation in the pot.
(6) For plants already affected by flooding, the wet soil clump should be removed, the wet mud should be taken out, and the plant should be placed in a shady and well-ventilated area. Water should be sprayed on the branches and leaves, and once the plant recovers, it should be repotted with fresh soil.
In addition, flood-tolerant plants include: Caladium, Cyperus alternifolius, Saxifraga, Ficus, Rhapis excelsa, Cordyline terminalis, Aspidistra elatior, Monstera deliciosa, Ficus elastica, Zantedeschia, hanging bromeliads, Commelina Communications, and various ferns, etc.
